Implementation Reference

• src/index.ts:926-936 (handler)

  MCP tool handler that invokes SiigoClient.updateInvoice with args.id and args.invoice, formats the result as JSON text content.
  private async handleUpdateInvoice(args: any) { const result = await this.siigoClient.updateInvoice(args.id, args.invoice); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], }; }
• src/siigo-client.ts:112-114 (handler)

  Core implementation that performs a PUT request to Siigo API endpoint /v1/invoices/{id} to update the invoice.
  async updateInvoice(id: string, invoice: Partial<SiigoInvoice>): Promise<SiigoApiResponse<SiigoInvoice>> { return this.makeRequest<SiigoInvoice>('PUT', `/v1/invoices/${id}`, invoice); }
• src/index.ts:397-408 (registration)

  Tool registration in getTools() array, including name, description, and input schema.
  { name: 'siigo_update_invoice', description: 'Update an existing invoice', inputSchema: { type: 'object', properties: { id: { type: 'string', description: 'Invoice ID' }, invoice: { type: 'object', description: 'Invoice data to update' }, }, required: ['id', 'invoice'], }, },
• src/types.ts:94-143 (schema)

  Type definition for SiigoInvoice used in updateInvoice parameters.
  export interface SiigoInvoice { id?: string; document: { id: number; number?: number; }; date: string; customer: { person_type?: string; id_type?: string; identification: string; branch_office?: number; name?: string[]; address?: any; phones?: any[]; contacts?: any[]; }; cost_center?: number; currency?: { code: string; exchange_rate: number; }; seller: number; observations?: string; items: Array<{ code: string; description?: string; quantity: number; price: number; discount?: number; taxes?: Array<{ id: number }>; }>; payments: Array<{ id: number; value: number; due_date?: string; }>; stamp?: { send: boolean; }; mail?: { send: boolean; }; global_discounts?: Array<{ id: number; percentage?: number; value?: number; }>; additional_fields?: any; }
• src/siigo-client.ts:41-59 (helper)

  Shared helper method that handles authentication, makes HTTP requests to Siigo API, and processes responses/errors.
  private async makeRequest<T>(method: string, endpoint: string, data?: any, params?: any): Promise<SiigoApiResponse<T>> { await this.authenticate(); try { const response: AxiosResponse<SiigoApiResponse<T>> = await this.httpClient.request({ method, url: endpoint, data, params, }); return response.data; } catch (error: any) { if (error.response?.data) { return error.response.data; } throw new Error(`API request failed: ${error.message}`); } }
